摘要： A method includes determining a lowest-score interpolation direction among a plurality of interpolation directions. The method further includes calculating a candidate pixel value by interpolating along the lowest-score interpolation direction. The method further includes applying a median function to a set of pixel values. The set of pixel values includes (a) the candidate pixel value, (b) at least one pixel value from a line of pixels that is immediately above a pixel location that is currently being interpolated, and (c) at least one pixel value from a line of pixel values that is immediately below the pixel location that is currently being interpolated.

摘要： More accurate frame-rate conversion is carried out in a simpler circuit configuration. Search areas SA+1 and SA−1 in each of which the pixel facing the interpolation position P0 of a pixel in an interpolation frame is taken as a central pixel are set in the current frame and immediately previous frame of an image signal, a set of pixels point-symmetrical to the interpolation position P0 in each of the search areas SA+1 and SA−1 are defined as pixel pairs, and differential luminance values between the individual pixels in the pixel pairs are calculated for each pixel pair. Of all these pixel pairs, only that having the minimum absolute differential value is selected as interpolation pixel pair, an interpolation frame is generated from the current frame and the immediately previous frame on the basis of the interpolation pixel vector of that interpolation pixel pair.

摘要： A method and system for image resample by spatial interpolation. The method and system allow more than simple angle interpolation by allowing spatial interpolation to be performed on small angle edges. Multiple interpolation directions are established. Once an interpolation direction is selected, verifications are performed on the selected interpolation direction in order to rule out erroneous selection. If the selected interpolation direction passes all verification, then spatial interpolation will be performed along the selected interpolation direction. Otherwise, a default interpolation direction is used as the interpolation direction.

摘要： A binarizer binarizes a video signal input from an A/D converter and a video signal output from a line memory using an average luminance value provided from a detection window video signal processor as a threshold value, and outputs a binary pattern. A reference pattern generater generates a plurality of reference patterns. An angle detector compares the binary pattern with each of the plurality of reference patterns, and outputs the angle of a matched reference pattern as angle information. An arc shape detector outputs the edge angle information of a picture based on a combination of the angle information of an interpolation scanning line including an object interpolation pixel and the angle information of interpolation scanning lines above and below the interpolation scanning line.

摘要： An image processing device and method can perform interpolation that reduces overshoot and ringing on a step edge while maintaining high frequency components. The image processing device includes a vertical step edge area determination unit that determines a vertical step edge area of an image, a horizontal step edge area determination unit that determines a horizontal step edge area of the image, and an interpolation unit that performs an interpolation based on the vertical step edge area and the horizontal step edge area.
